Chrome frame: whats it worth?

I have a contact that has a 1970 Raleigh Gran Sport(s?) frame in my size, full chrome. Nervex lugs except fork, 3 main tubes 531. If the chrome looks good, what would you consider market to be, or if you thought a chrome frame would be interesting but can't afford a vintage Paramount, what would you give for it. My effort to not let my enthusiasm (hoarding tendency) get the best of me.
